Parents are arrested when police officers make a horrifying discovery in a backyard fire pit after their father bragged about killing and burning two children they had kept hidden from the world

An Indiana couple was arrested after police officers made a gruesome discovery in their backyard fire pit.

Officers began investigating Steven Valle, 31, and Samantha Sebella, 25, on Sept. 20, when Valle allegedly confessed to friends that she killed two undocumented children and burned their bodies in her backyard fire pit in Wheatfield, reports Fox32.

The children had no documents such as a birth certificate or social security number and therefore were never included in government records.

But when deputies from the Jasper County Sheriff’s Office arrived at the Wheatfield home where Valle and Sebella once lived, they found “partial bone fragments” that a specialist in Indianapolis was able to determine were human, according to Law & Crime.

The couple was then taken into custody on Thursday and charged with murder, neglect of a relative resulting in death, abuse of a corpse, obstruction of justice and failure to report a corpse.

Samantha Sebella, 25, and Steven Valle, 31, were taken into custody Thursday for allegedly killing their children and burning their bodies

According to authorities, the couple initially denied any knowledge that children had been burned in the backyard fire pit when officers found them at a Newton County hotel on Sept. 20.

They admitted they had a child for whom they did not have a birth certificate because the birth occurred at home and the child was not documented, according to court documents obtained by Fox 59.

The couple also allegedly told officials that there had never been a miscarriage or stillbirth, and law enforcement conducted a records review with the Jasper County Health Department and found that there were no records to suggest that Sebella ever had gave birth to a child.

Still, police took their cellphones, which they reportedly used to uncover numerous messages indicating that Valle had killed and burned several children.

“You killed my kids because you suck, you never loved me,” one message said, according to court documents.

“You killed our babies, I have DNA in my body forever,” read another message between Sebella and Valle.

A third undocumented child was then removed from her care, law enforcement said.

Then on Sept. 30, the sheriff’s office, Indiana State Police and the Jasper County Coroner’s Office, along with two cadaver dogs, raided the Wheatfield home where they had previously lived. Valle and Sabella were reportedly evicted from the property earlier this year.

According to Fox 59, the dogs marked a fire pit and a pile of ash near the garage, prompting investigators to dig up a portion of the backyard with shovels and uncover the bone fragments.

Valle admitted on Oct. 3 that Sebella gave birth to a boy in 2018, court documents show.

He told officers that Sebella gave birth to the child while he was away and claimed that when he returned home, he found Sebella passed out and the child lying between her legs.

The child was neither awake nor breathing, Valle said, claiming he cleaned the newborn, wrapped him in a blanket and put him in a box.

Valle allegedly went on to say that he buried the child in his backyard after three days because he “knew the child would not come back to life.”

The suspect then told officers that Sebella had become pregnant a second time and had given birth prematurely in a bathtub while he was at work.

He said the child was dead and wrapped in a blanket when he got home and buried him in the backyard near the first, according to court documents.

Police also said Valle told them the children had been buried for about three to five years before he dug them up and burned them in the fire pit.

He allegedly added that he saved some of the ashes to make a necklace.

As the investigation continued, officers learned that Valle and Sebella had been physically violent toward one another and determined that Sebella had taken no action to protect her two deceased children, her living child, or herself from the violence.

Police also said they made no effort to inform authorities about the children’s deaths, burial or cremation.

Valle and Sebella are currently serving their sentences at the Jasper County Detention Center, where they remain without bond.
